The motto of emergency declaring is to weaken the spreading of viruses.

According to officials, the declaration was due to "the potential for this virus to spread to countries with weaker health systems which are ill-prepared to deal with it."

World's highest populous country, China, with 1.4 billion people, has taken extreme measures to try to stop the disease.

Wuhan, the epicentre of the virus, has stopped travel in and out of that city and surrounding ones.

The outbreak killed one Indian student in the country, becoming the first country outside of China having a death out of the virus.

Germany confirmed with five cases, where in Australia nine and one in Sri Lanka. Also, other countries like Japan, Vietnam, Singapore, Thailand, Nepal, France, the US and Canada are being hit by the novel virus.

WHO declared a public health emergency of international concern as describing the outbreak as "an extraordinary event", which constitutes public health risk to other States through the international spread of disease.

Criteria of declaring an emergency

A group of experts of WHO call PHEIC or "public health emergency of international concern," to trigger global action.

There are two criteria to define an outbreak as PHEIC.

One, the outbreak must pose a risk to more than one country.

The second, the outbreak requires "a coordinated international response."

According to WHO's official definition, this means a "situation that is serious, unusual or unexpected."

Implications

A PHEIC declaration in the host country leads to a boost in public health measures, funding and resources to prevent and reduce international spread.

The measures include restrictions on trade and travel, including airport screening of passengers.
